Owners of cryptocurrency wallets have sued two web and data services companies, claiming they should have been warned sooner that hackers accessed their personal information and used it to scam and threaten those same customers.

The complaint filed April 1 in the District of Delaware federal court is seeking class action status against Shopify Inc. and TaskUs Inc., alleging the companies were negligent in preventing and addressing the 2020 data breach of information for 272,000 Ledger SAS hardware wallet users, about one third of whom live in the United States.
